Power Button

The Power button is most important. If you can't find this one, you won't get too far with your computer! This is either a push button or a flip switch that turns on the computer. Computers usually have this on the front, but some models may have it on the side or even the back of the computer. There is an LED light to show you that the power is on.

Usually pushing the power button turns the computer on and a second push of the button will turn it off. But on other computers, the button only turns the computer on. There is a second power switch on the back for turning it off when a shut down command from the operating system doesn't do the job.

Be careful not to turn off the computer with the power button or switch while the computer is working. You can destroy documents and even corrupt system files so that the computer won't work right anymore, if it works at all.
